Sol 1799, August 28, 2017. Curiosity’s Navcam looks back toward the north and shows how far up the slope of Mt. Sharp the rover has driven. The low, dark mesas in the middle distance are the Murray Buttes, which rose high above Curiosity as it was driving among them a year ago. Beyond the buttes lies the floor of Gale Crater, which reaches the crater’s northern rim in the far distance.
Below is a five-frame Mastcam composite of the ridge lying in front of Curiosity, showing its thin sedimentary layering and crosscutting mineral veins. (Click either image to enlarge it.)
